Purpose & Fit

GP Thunder H11B bulbs are 55W 12V halogen replacements that emit a 7500K plasma-white hue for low-beam, high-beam, fog or daytime-running use. The H11B base matches factory sockets on listed Kia models including Borrego, Optima and Sedona, so owners seeking whiter output without rewiring can install them directly.

What the Pair Changes

Two bulbs per pack let both headlamps or fog lamps be upgraded at once, keeping colour and intensity balanced across the front end. The blue-coated quartz glass filters the beam to a crisp white tone rated at 7500K, reducing the yellow cast of standard halogens while staying within the original 55 watt draw.

Install Notes & Common Issues

Installation is a direct swap: remove the old H11B capsule, insert the new bulb and reconnect the factory plug. Handle the quartz envelope with clean gloves to avoid hot spots that shorten life, and verify the headlamp housing seals properly so moisture cannot enter the reflector bowl.

Questions about this item

How often will the 55W 12V H11B capsules need replacing?

Halogen capsules degrade with heat cycles; plan to swap both bulbs together once light output noticeably dims or one filament fails.

What stops the 7500K bulbs from running continuously on a long drive?

The 55W draw at 12V creates steady heat in the quartz envelope; the headlamp housing’s thermal limit is reached before the bulb itself fails.

How much heat and noise do the pair produce during all-day use?

Each 55W capsule turns most power into heat inside the reflector; expect warm lenses and zero fan noise because there are no moving parts.
